Defensive publication

ABSTRACT

PARTICULATE SUBSTANCES CONTAINING POLYMERIZABLE OLEFINIC UNSATURATION USEFUL AS REACTIVE FILLERS FOR RESINS WHICH ACHIEVE FINAL FORM AND USEFUL PROPERTIES BY POLYMERIZATION OF OLEFINIC UNSATURATION. THE REACTIVE FILLERS ARE PARTICULARLY USEFUL AS MODIFIERS FOR UNSATURATED POLYESTER RESINS. IN THIS APPLICATION, THE REACTIVE FILLERS CAN BE USED DURING FORMATION OF A SHAPED ARTICLE, IMPART SPECIAL PHYSICAL PROPERTIES SUCH AS IMPROVED IMPACT RESISTANCE, IMPART IMPROVED DIMENSIONAL STABILITY, AND IMPART IMPROVED APPEARANCE. THE REACTIVE FILLERS ARE MADE BY POLYMERIZING SUBSTANCES OR MIXTURES WHICH CONTAIN MORE THAN ONE TYPE OF OLEFINIC UNSATURATION, AT LEAST ONE OF WHICH CAN FORM COPOLYMERS BUT WILL NOT FORM HOMOPOLYMERS UNDER THE REACTION CONDITIONS USED TO MAKE THE FILLER AND WHEREIN A PART OF THIS TYPE OF UNSATURATION REMAINS IN THE REACTIVE FILLER MATERIAL AND IS AVAILABLE FOR SUBSEQUENT POLYMERIZATION REACTIONS.

PUBLISHED DECEMBER 2, 1975 T941,004 REACTIVE FILLERS FOR UNSATURATEDRESINS Clarence C. Dannelly, Rte. 8, Cochise Trail, Kingsport, Tenn.37664 Filed Aug. 1, 1974. Ser. No. 494,020 Int. Cl. C08f 43/08 us. Cl.260-862 No Drawing. 9 Pages Specification Particulate substancescontaining polymerizable olefinic unsaturation useful as reactivefillers for resins which achieve final form and useful properties bypolymerization of olefinic unsaturation. The reactive fillers areparticularly useful as modifiers for unsaturated polyester resins. Inthis application, the reactive fillers can be used during formation of ashaped article, impart special physical properties such as improvedimpact resistance, impart improved dimensional stability, and impartimproved appearance. The reactive fillers are made by polymerizingsubstances or mixtures which contain more than one type of olefinicunsaturation, at least one of which can form copolymers but will notform homopolymers under the reaction conditions used to make the fillerand wherein a part of this type of unsaturation remains in the reactivefiller material and is available for subsequent polymerizationreactions.
